To all whom it may concern:

Beit known that "I, HEINRICH 'ELsNnR, a subject of Germany,t and residing at Dresden-A, .Dobelnerstrasse .128, Germany, have inventedcertain new and-useful Improvements in Machinesiffor Cutting Several Individual Cigarettes from Previously-Cut Cigarette Rods, of which the following isa specificationg invent-ion relates to a machine 'for cutting a multiplicity of prcviouslycut cigarette'rods into proper-"lengths for several individual cigarettes. The hitherto very limited capacity of .all existing cigarettemaking machines is considerably increased through this new machine so as to render the manufacture of cigarettes more profitable and productive. I

The mac'h'ne can be attached to anyexisting cigarette-making machine or used in combination with anew machine especially constructed for this purpose.

one form of the invention is i'llustrated' in the. accompanying -drawing,-i-n whichFigure 1 is .a'side view ofthe entire. machine; ,Fig. 2 is a side view ftrom another direction, and Fig. 3 a view of-the machine from above. a

In thedrawing 1 is a main "shaft resting in bearings 2fctl1d 3 carrying the drum 4 which on its entirecircumference is provided with grooves 5. Each of these grooves 5 can hold a cigarette rod of any desired length equal to the total'lflength of a multiplicity of individual cigarettes. 6 are metallic guide bandswhichkeepthe cigarette rods in position during the rotation of the drum; and 7 is a device for putting the cigarette rods, one after the other, into the corresponding grooves 5 of the drum 4.

The feeding device may be of any of the existing types and the modification shown in accompanying drawing is nothing but a mere diagrammatic arrangement to point out the spot where the feeding device for cigarettes is attached. 8 is a curved guide for adjusting the position of the cigarettes in the drum 4, and 9 are circular knives arranged so as to cut the cigarette rods in the drum at a certain definite point. v

It is evident that one, two or more circular knives may be arranged at the proper distance from each other to cut simultaneously the cigarette rods into proper lengths for two, three or more individual cigarettes.

10-;is an endless conveyor 'belt which .at 11 receives the cigarettesdropping out of the grooves 5 of the drum 4. I21aretl1ee-iga'rette rods.

"It is essential that the driving media for the drum 4:, the knives 9 and the endless conveyor belt 10 are controlled by the same main drive. The machine is driven in the following manner:

22 lea-driving belt or chain which prefer- :ably is connected to the main drive of the cigarette-making machine and transmits ower; to the shaft 25, which drives abeveled pinion 21 which is in engagement with a secondbeveled pinion 26. i The latter transmits its rotary motion to the spindle27, to which is secured the worm 23 which cooperates with the worm wheel 24 on the shaft 1 ofkthe machine, causing rotation of shaft 1 and drum 4. Y

Theknives 9 are driven as followsz shaft 25 carries adisc wheel which is connected to disc wheel 17 by means of a belt. Disc wheel 17 and disc whe'ellG are carried by the shaft 18 of the machine. 14 is a holder on which shaft 13 rests which in turn car- 'r'ies knives 9 and disc The latter is connected to disc 16 by means of belt. As the result of above arrangement belt drive 22 causes the drum 4 and knives'9' to rotate, while the speedof the knives maybe regulated'uat'w'ill by selecting varying sizes of thediscs20, 17, 16 and25.

p In the same manner the conveyer belt may be rotated by suitable means from the main "drive 22. v i

The arrangement works as follows: the previously cut cigarette rods which may be equal in length to two, three or more cigarettes of ordinary size are put into the drum 4 so as to fit one cigarette rod each into one of the grooves 5 of the drum 4, while the guides 8 cause the cigarette rods to be in the proper position before meeting the knife 9. During the rotation of the drum 4 the grooves 5 of the drum, one after another, are led past the feeding device 7 so as to permit each groove to receive one rod each and to convey the latter to the rotating knives 9. The rods are held in their respective grooves by means of the guide bands 6 until they reach point 11 where they are cut into individual cigarettes of the pro er length, drop on the guide band 10 an are carried away by the latter.

The invention is naturally not limited to the particular form shown and described above but can be applied broadly to a machine for cutting a multiplicity of previously cut cigarette rods into proper lengths for several individual cigarettes. The constructive arrangement referred to above may be varied in its essential parts, for in stance instead of the rotatingdrum which brings the cigarette rods to the knife any suitable feeding device may be employed in order to directly or indirectly deliver the cigarette rods by means of any suitable media within reach of the cutting or sepa ating devices.

It has been found best to move the cigarette rods towards the cutting devices, but it would also be possible to move the cutting device towards the cigarette rods which would then be in an axial position of rest.

If several cutting devices are employed, it is advisable, in view of the varying wear and tear of the individual cutting devices, to mount each cutting device separately and adjustably in the direction of the cigarette rods; each cutting device may also be driven separately.

Furthermore, if several cutting devices are employed, they must be adjustable in axial direction in order to cut cigarettes of varying length.

The adjust-ability of the said cutting devices may be obtained in any suitable manner.

It is one of the features of the invention that the machine may be attached to any existing cigarette-making machine without necessitating essential changes.

I claim 1. A machine for the manufacture of individual cigarettes from previously cut cigarette rods characterized by a rotating drum, provided at its periphery with grooves into which the said cigarette rods drop after leaving the cigarette-making machine; and furthermore means for adjusting the cigarette rods so that the ends thereof will lie in one plane, guide bands around a part of the circumference of the drum, circular knives for dividing the cigarette rods into individual cigarettes, and a conveyor belt for carrying away the said individual cigarettes.

2. A machine for the manufacture of individual cigarettes from previously cut cigarette rods characterized by a rotating drum, provided at its periphery with grooves into which drop the said cigarette rods after leaving the cigarette-making machine; furthermore a bent guide bar, guide bands around a part of the circumference of the drum, circular knives for dividing the cigarette rods into separate, individual cigarettes, and a conveyor belt for carrying away the said individual cigarettes, while the rotation of the drum, the knives, and the conveyor belt is caused by a common drive. 7 8. A machine for the manufacture of individual cigarettes from previously cut cigarette rods characterized by a rotating drum, provided at its periphery with grooves into which drop the said cigarette rods after leaving the cigarette-making ma chine; and furthermore a bent guide bar, guide bands around a part of the circumference of the drum, circular knives for dividing the cigarette rods into separate, individual cigarettes, and a conveyor belt for carrying away the said individual cigarettes, while for the purpose of cutting cigarettes of varying length from one and the same rod the knives are axially adjusted to each other.

In testimony whereof I affix my signature in presence of two witnesses.

HEINRICH ELSNER.
